I am new at this php+HTML5+jquery mobile trying to build a web app with mysql connection.
Somewhere along the way... I use a php file to "generate" a HTML file containing 3 select boxes, where the user will have to choose a day of the month in order to continue. I designed the destination page using javascript + HTML all went well, then I echoed the entire page in a php file (that I call+process somethings in order to receive the page). The problem I have is with escaping a string I suppose. I mean, if I comment these lines, the page works (not as it should, but at least the page gets shown). If I do not comment them, the jquery shows an alert saying "Error loading page"
The html that works just fine is:
<html>
<head>
<title>Select</title>
<script type="text/javascript" src="http://code.jquery.com/jquery-1.9.1.min.js" />
</head>
<body>
<span id="day-select">
<select id="day">
<script type="text/javascript">
function LastDayOfMonth(Year, Month) {
return new Date( (new Date(Year, Month+1,1))-1 );
}
var nextmonth = new Date();
nextmonth.setHours(0, 0, 0, 0);
nextmonth.setMonth( nextmonth.getMonth() + 1 );
var nextziua = nextmonth.getDate();
var ultimazidt = LastDayOfMonth(nextmonth.getFullYear(), nextmonth.getMonth());
var ultimazi = ultimazidt.getDate();
var ziuaselect = nextziua;
var count = ultimazi;
var ziua=1;
while(ziua <= count){
if(ziua == nextziua){
document.write('<option value="'+ziua+'" selected="selected">'+ziua+'</option>');
}
else{
document.write('<option value="'+ziua+'">'+ziua+'</option>');
}
ziua++;
}
</script>
</select>
</span>
<br><br>
</body>
</html>
So, the above html file... works just fine, but when I try it from an echo in a PHP file, all goes to hell right at this line:
document.write('<option value="'+ziua+'" selected="selected">'+ziua+'</option>');
I mean:
echo ' <html>';
echo ' <head>';
echo ' <title>Select</title>';
echo ' <script type="text/javascript" src="http://code.jquery.com/jquery-1.9.1.min.js"></script>';
echo ' </head>';
echo ' <body>';
echo ' <span id="day-select">';
echo ' <select id="day">';
echo ' <script type="text/javascript">';
echo ' function LastDayOfMonth(Year, Month) {';
echo ' return new Date( (new Date(Year, Month+1,1))-1 );';
echo ' } ';
echo ' var nextmonth = new Date();';
echo ' nextmonth.setHours(0, 0, 0, 0);';
echo ' nextmonth.setMonth( nextmonth.getMonth() + 1 );';
echo ' var nextziua = nextmonth.getDate();';
echo ' var ultimazidt = LastDayOfMonth(nextmonth.getFullYear(), nextmonth.getMonth());';
echo ' var ultimazi = ultimazidt.getDate();';
echo ' var ziuaselect = nextziua;';
echo ' var count = ultimazi;';
echo ' var ziua=1;';
echo ' while(ziua <= count){';
echo ' if(ziua == nextziua){';
echo <<<EOT
document.write('<option value="'+ziua+'" selected="selected">'+ziua+'</option>');
EOT;
echo ' }';
echo ' else{';
echo <<<EOT
document.write('<option value="'+ziua+'">'+ziua+'</option>');
EOT;
echo ' }';
echo ' ziua++;';
echo ' }';
echo ' </script>';
echo ' </select>';
echo ' </span>';
echo ' <br><br>';
echo ' </body>';
echo ' </html>';
So this code is generating the contents of a SELECT box, with day numbers 1-30, 1-31 or 1-29 depending on the month. Also it makes "selected" the current day. Again... all goes fine when doing it directly in HTML, but when I try to echo it... everything stops. because of that document write. I tried escaping single quotes or escaping double quotes. Same result. That's why I adopted the heredocs method. But as it seems it is still useless for my problem. I paid attention to the heredocs syntax: - no spaces after
<<<EOT
no spaces after final EOT;
The last one (EOT;) is on a new line Still, nothing works. Can anyone tell me what am I doing wrong? Any help will be appreciated. Thank you
